The ICS function responsible for documentation of mutual aid agreements is the Finance/Administration Section. This section handles all financial, administrative, and cost aspects of the incident, including documenting mutual aid agreements to ensure proper tracking and management of resources and costs. However, there are some sources indicating that the Planning Section also plays a role in documentation related to mutual aid agreements by collecting and evaluating operational information. The strongest consensus is that Finance/Administration is responsible for the official documentation of mutual aid agreements, while Planning may assist in the broader information management and coordination efforts related to those agreements.
